what kind of grating is used here and what is the pixel count?

hi, what are the SALT properties of the image created?
Size of image?
Attitude (which way the image is oriented compared to the object)
Location of image
Type (is it virtual or real)?
Thanks in advance!

great tutorial, thank you.


I have 2 questions,
1) the monochrome camera senses 2 dimensional image. As I understand one dimension gives spectral signature of a pixel in the observed line, is that true?
I will open the question, for example monochrome camera observes 600x400 pixels of data. In this case, do you have 400 band spectral information of 600 pixels ?
2) After image acquisition, how do you know the wavelength of the bands? In the image of monochrome camera, how do you determine which pixel corresponds to which wavelength?
